The Thendara Mountain Club Harriman group camp is based in a rustic lodge built atop Hasenclever Mountain in the Harriman Section of the Palisades Interstate Park.  

Thendara is a non-profit social group who’s members enjoy hiking, boating, swimming and general outdoor activities.  Thendara was formed as a hiking club under it parent group the Green Mountain Club in 1916 as the NY Section GMC.

Our historic cabin, built in 1920, is used for dining, socializing, reading or enjoying a blaze in the fieldstone fireplace.  Our Harriman group camp cabin has a screened-in porch, sleeping rooms and a complete kitchen.  The  TMC “bunkhouse,” a screened sleeping house, adds to the warm weather enjoyment of the camp.

Tent sites round out the overnight camping options.

Thendara Mountain Club is operated on a year-round, cooperative basis.  TMC Members volunteer to host a weekend or midweek at the camp. The participants share the work of creating a meal and then enjoying the fruit of their labors. Friendships are formed while working side by side in the kitchen and breaking bread together.

Harriman State Park hiking trails start at our doorstep, and a short walk down the hill leads to Lake Tiorati.

Our Harriman Group Camp private facilities on Lake Tiorati include canoes, kayaks, sailboats and a swimming area.

The winter brings opportunities to hike, showshoe, cross-country ski, or relax by the warm fireplace.
